'Able' in the Bible

Therefore, putting aside all moral uncleanness and wicked excess, welcome with humility the implanted message which is able to save your souls.

What [is] the benefit, my brothers, if someone says [that he] has faith but does not have works? That faith [is] not able to save him, [is it]?

For we all stumble [in] many [ways]. If anyone does not stumble in what he says, he [is] a perfect individual, able to hold in check his whole body also.

but no human being is able to tame the tongue. [It is] a restless evil, full of deadly poison.

A fig tree is not able, my brothers, to produce olives, or a grapevine figs. Neither can a saltwater spring produce fresh water.

You desire and do not have; you murder and are filled with envy, and are not able to obtain; you fight and quarrel. You do not have because you do not ask.

There is one lawgiver and judge who is able to save and to destroy. But who are you to judge your neighbor?
